open_namei() will, in the future, need to take mount write counts
over its creation and truncation (via may_open()) operations. It
needs to keep these write counts until any potential filp that is
created gets __fput()'d.
This gets complicated in the error handling and becomes very murky
as to how far open_namei() actually got, and whether or not that
mount write count was taken. That makes it a bad interface.
All that the current do_filp_open() really does is allocate the
nameidata on the stack, then call open_namei().
So, this merges those two functions and moves filp_open() over
to namei.c so it can be close to its buddy: do_filp_open(). It
also gets a kerneldoc comment in the process.

This patchset is a medium scale rewrite of the export operations interface.
The goal is to make the interface less complex, and easier to understand from
the filesystem side, aswell as preparing generic support for exporting of
64bit inode numbers.
This touches all nfs exporting filesystems, and I've done testing on all of
the filesystems I have here locally (xfs, ext2, ext3, reiserfs, jfs)
This patch:
Add a structured fid type so that we don't have to pass an array of u32 values
around everywhere. It's a union of possible layouts.
As a start there's only the u32 array and the traditional 32bit inode format,
but there will be more in one of my next patchset when I start to document the
various filehandle formats we have in lowlevel filesystems better.
Also add an enum that gives the various filehandle types human- readable
names.
Note: Some people might think the struct containing an anonymous union is
ugly, but I didn't want to pass around a raw union type.
